How to encrypt text
To encrypt text:
1. Double-click on Encryption and Decryption Pro desktop icon.
2. Click 'Tools' button and select 'Encryption' item.
3. Put the radio button next to 'Text'
4. Enter or paste the text you want to encrypt in 'Text you want to encrypt' area.
|
Note:
• For Windows Vista/XP/2003/2000 max length of text you can encrypt is 524224 characters.
• For Windows 98/ME max length of text you can encrypt is 32704 characters.
|
|
5. Click 'Encrypt' button.
6. Enter password for encryption and confirm it. |
 Attention: You have to remember password as it will be needed for decryption.
|
|
|
Note:
"Encrypt with password check confirmation" option is on (by default this option is on after installation, then it remembers its last state)
If "Encrypt with password check confirmation" option is on, your password hash is stored in the encrypted text. Later, when you decrypt the text, the password you enter is hashed and compared with the stored password hash. And, in case, the hash of the password you enter matches the stored password hash, your encrypted text will be decrypted. If you enter wrong password, you'll get en error message "Wrong password".
"Encrypt with password check confirmation" option is off
To mitigate the threat of trivial Brute Force attacks on the encrypted text, you can encrypt your text the way it doesn't store password hash. If you turn off "Encrypt with password check confirmation" option, it prevents program from storing password hash in the encrypted text and makes Brute Force attacks harder.
In this case, if you enter wrong password for decryption, you won't see any error message, your text will be "decrypted" using wrong password and you will see abracadabra instead of the real text.
Don't worry if you decrypted the text with wrong password, your original encrypted text is still stored in the "Encrypted text you want to decrypt" area and you can decrypt it with the correct password.

If "Encrypt with password check confirmation" option is on, your password hash is stored in the encrypted file. Later, when you decrypt the file, the password you enter is hashed and compared with the stored password hash. And, in case, the hash of the password you enter matches the stored password hash, your encrypted file will be decrypted. If you enter wrong password, you'll get en error message "Wrong password".

To mitigate the threat of trivial Brute Force attacks on the encrypted file, you can encrypt your file the way it doesn't store password hash. If you turn off "Encrypt with password check confirmation" option, it prevents program from storing password hash in the encrypted file and makes Brute Force attacks harder.
Attention: Be careful while entering password. If you enter wrong password for decryption, you won't see any error message, your file will be "decrypted" using wrong password and it will be overwritten with wrong information and there is no way to recover it except if you have backup. To protect your file information, we recommend you decrypt the file to another file.
